當研究者想要了解態度量表中不同組間之態度分數是否有所差異時，一個常見的分析方法為變異數分析。然而，變異數分析需要建立在資料服從常態分配之假設上，態度量表之資料類型卻很明顯地不符合此一假設。而非針對連續型資料所推導出來的 統計量，應該是較適合處理序列或是等距尺度等非常態資料之檢定方法。本研究主要之目的即為探討利用 統計量以及利用變異數分析兩者所作出之檢定結果差異為何。過去相關研究皆假設態度量表背後存在一連續潛在變數，本研究則直接由間斷型分配出發。在公式推導上，我們發現 統計量與變異數分析中之 統計量存在一對一對應之關係。雖然兩統計量近似之分配不同，但兩統計量所對應之p值卻始終非常接近。若以0.05為顯著水準， 統計量與 統計量之檢定結果幾乎完全相同。當需要檢定不同組間在多題上之看法是否具有差異時，我們比較了將屬於同一主題之各題分數加總，然後依照單變量變異數分析之方法進行檢定，以及多變量變異數分析法、羅吉斯迴歸分析法等三種方法。根據我們的模擬結果，若各組在各題之態度皆很類似，則利用ANOVA進行分析可以得到較低的型一誤差；若各組在各題之態度不太一致，且有左右偏分配互相抵銷的情形，則利用MANOVA或是羅吉斯迴歸分析法才能夠維持住很高的檢定力。 / In social science literature, we frequently found that ANOVA techniques were utilized to analyze Likert-type response data. However, one of the three basic assumptions behind ANOVA is that response variable is normally distributed, and Likert-type data apparently do not share this property. In this study, we compare the performance between statistic associated with ANOVA with Mantel- Haenszel statistic, a statistic aimed at handling categorical data. We found that statistic and statistic have one-to-one relationship. Although these two statistics can be approximated by distribution and Chi-square distribution respectively, their p values are quite close to each other. At the significant level of 0.05, and statistics almost have the same testing results. In addition to analyzing a single Likert-type response question, we would also like to analyze a set of Likert-type response questions that probably represent a specific concept. We propose two alternatives here. The first one is MANOVA, and the second one is logistic regression analysis. According to the simulation results, using the ANOVA approach is slightly better in terms of the type I error rate if the responses have similar structures among questions. On the other hand, using MANOVA or logistic regression analysis would maintain higher power whenever the responses have different structures among questions.

This diploma thesis deals with the rating scales, which are widely used in the attitude measurement, namely with the impact of their length (number of scale points) on measurement, both in terms of cognitive processes in the minds of respondents and impact on the data. Hypotheses, formulated on the basis of the literature and tested using data obtained from a split ballot experiment and cognitive interviews, are related to the comparability of results, distribution of responses and task demands. The Net Promoter Score from the environment of market research, expressing respondent's willingness to recommend a service or company used, is used as an application example. It originally uses 0 to 10 eleven-point scale which is here compared to five-point scale from 1 to 5 using various recoding and rescaling techniques. Analysis shows that rating on eleven-point and five-point scales means two different cognitive tasks for respondents (eleven-point scale is a bit more demanding but more accurate in respondents perception) and that the data differ from each other in terms of distribution of responses - on short range scale, midpoint and extreme positive category are selected more often, while on eleven-point scale, milder positive points are used more often.

Text in Afrikaans / Vrouemisdaad is 'n komplekse sosiale verskynsel. 'n Aspek van vrouemisdaad wat in die onderhawige proef skrif ondersoek word, is om aan die hand van bestaande teoriee te probeer verklaar waarom vroue soveel minder misdaad as mans pleeg. Ten einde antwoorde op die vraag te vind, is 'n kwantitatiewe ondersoek na die gemeenskap se houding rakende die vrouemisdadiger en 'n kwalitatiewe ontleding van die beskikbare literatuur gedoen. 'n Intensiewe verkennende studie van die beskikbare literatuur het getoon dat die gemeenskap, navorsers en akademici bepaalde persepsies huldig oor die vrouemisdadiger wat nie altyd met die werklike beeld strook nie. Alhoewel die getalle van vrouemisdadigers deur die jare toegeneem het, het die tipe misdade wat vroue pleeg weinig verander en die omvang van vrouemisdaad proporsioneel tot die bevolking dieselfde gebly. Geen enkele teorie of benadering op sigself bied 'n algemene verklaring vir die verskynsel van vrouemisdaad nie; dit kan hoogstens as gedeeltelike verklaring dien. 'n Algemene verklaringsmodel vir vrouemisdaad is egter opgestel wat terselfdertyd as samevatting van die geselekteerde teoriee dien. Met behulp van die argivale metode is 'n profiel van die gekommitteerde vrouemisdadiger saamgestel om 'n basiese kennissisteem van die vrouemisdadiger daar te stel. Statisties beduidende verbande is gevind tussen die karakteristieke van die blanke gekommitteerde vrouemisdadiger se huwelikstaat, aantal kinders en bedrog. Die kwantitatiewe ondersoek bestaan uit die ontleding van 516 respondente se persepsies oor die vrouemisdadiger. Uit die resultate van verskeie statistiese tegnieke blyk dit dat die ondersoekgroep, wat blanke respondente van vier voorstede uit struktuurstreekplansel 22 van Pretoria verteenwoordig, bepaalde persepsies en opvattings aangaande die vrouemisdadiger het. Die persepsiemeting het aan die lig gebring dat daar verskille in persepsies bestaan oor die vrouemisdadiger en vrouemisdaad in die blanke gemeenskap bestaan. Hierdie persepsies stem nie ooreen met die beeld wat blyk uit die onderhawige navorsing nie. Statisties beduidende verskille in persepsies tussen manlike en vroulike respondente van die ondersoekgroep is ook gevind. Daar bestaan verder statisties beduidende verskille tussen respondente van verskillende voorstede, onderwyspeile, taalgroepe, en ouderdomsgroepe. / It can be said that female crime is a complex phenomenon.

[pt] O treinamento de habilidades sociais (THS) pode contribuir de forma significativa para o desenvolvimento das pessoas, tanto no âmbito pessoal como profissional. As atitudes das pessoas frente a participar de um THS revelam o quanto elas são favoráveis a esse treinamento e juntamente com normas subjetivas e percepção de controle, podem explicar o comportamento de realizar efetivamente um THS. O objetivo desse estudo foi elaborar e buscar evidências de validade de quatro escalas para aferir: intenção comportamental, normas subjetivas, percepção de controle e atitude frente a participar de um THS. Participaram da pesquisa 808 adultos brasileiros, média de idade de 32,3 anos, 64 por cento mulheres. Os resultados mostraram instrumentos unifatoriais, com índices psicométricos satisfatórios. A atitude correlacionou-se positivamente com a intenção de fazer um curso de habilidades sociais, com cinco das seis dimensões dos valores básicos e com motivação para aprender. Normas subjetivas e percepção de controle correlacionaram-se positivamente com intenção comportamental. E intenção comportamental correlacionou-se positivamente com motivação para aprender. Reuniram-se diversas evidências de validade que corroboram a adequação dos instrumentos para aferir os construtos. Ainda, ficou evidenciado que as mulheres e as pessoas que já tinham participado de um THS mostraram níveis maiores na atitude frente a participar de um THS. O estudo aponta para possibilidades de uso dos instrumentos em ambientes acadêmicos e organizacionais. / [en] Social Skills Training (SST) can significantly contribute to people s development, both personally and professionally. People s attitudes toward participating in an SST reveal how much they see this training favorably, and along with subjective norms and perception of control, can explain the behavior of effectively taking part in an SST. The objective of this study was to elaborate and search for evidence of the validity of four scales measuring: behavioral intention, subjective norms, perception of control and attitude towards taking part in an SST. Participants were 808 Brazilian adults, with mean age 32.3 years, and 64 percent being women. Our results showed a one-factor instrument with satisfactory psychometric indices. The attitude toward SST correlated positively with the intention of taking part in an SST, with five of the six dimensions of basic values, and with general motivation to learn. Subjective norms and perception of control were positively correlated with behavioral intention. And behavioral intention correlated positively with motivation to learn. Evidence of validity was gathered to corroborate the suitability of the instrument to measure the construct. Also, it was found that women and people who had already participated in an SST showed higher levels in their attitude towards participating in an SST. The study points to the possibility of using these instruments in organizational and academic environments.
